Cement grinding Vertical roller mills versus ball mills

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the CNC Milling: Introduction to cutting tools wikimalBall nose end mills are used on workpieces with complex surfaces.

This means they can handle harder or more durable materials like stone and steel, which may damage other types of milling equipment.


Pulverizer - Wikipedia

The ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD-4772,Gold extraction - QueensMineDesignWikiGenerally ball mills are utilized after an initial material crushing or grinding has occurred.
